Specification of Letters Patent.

Application filed larch a1, 1911, Serial 10. 618,096. Renewed January is, 1914. Serial mt mm;

To all whom it may concern Be it known that I ISIDOR KITSEE, a citizen of the United tates, residin in the city. of Philadelphia, county of hiladelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Relays, of which the following'is a specification.

My invention relatesto relays, and more particularly to polarized relays of the movin coil type.

he relay herein disclosed and claimed is type disclosed and claimed in my prior U. 5. Patent No. 963,374, granted July 5 1910.

The relay herein disclosed is of general application, but it is particularly useful w ere an extremely sensitive relay is required, and is particularly useful in the re ceivi apparatus associated with a long line or cab e, such as a submarine cable, or any other line orcircuit, having relatively great capacity; and when used in connection with such a line or circuit or submarine cable, I have beenable to transmit thereover at high rate of Speed telegraphic messages represented by Morse characters, and have been able to translate these charactersby an aplication of the relay herein disclosed into orse characters on an ordinary sounder, it being remembered that the practice heretofore on submarine cables has been to use a.

siphon recorder or other device, and so far as I am aware, the transmission of Morse characters over a long submarine cable and translation into Morse characters by an ordinary sounder has not been accomplished. Similar to the relay of my aforesaid patent, my present relay has for its moving elemerit a plurality of coils dispomd at an angle with I t to each other and moving as'a unit disposed in a suitable magnetic field. v

of construction hereinafter described and claimed. V

For an illustration of one of the forms my invention may take, reference is to be had to the accompanying drawings, inwhich: Figure '1 is a top plan view of my relay. Fig. 2. is a. cross being shownin elevation. F- 3 is a -per-' tive ,view of a air of fi d poles 2E3; pole pieces: ig. 4; is a side eleva- -to pole tips 6.

My present. invention relates to featuressectional view, some tional view of the central core and its supporting means, and the means for supportin the moving system. Fig. 7 is a horizonta sectional view taken on the line BB, of Fig. 6. Fig. 8 is a perspective view of a member, preferably of insulating material, for supporting the stationary terminals of the moving system. Fig.

Fig. 10 is a perspective view of a similar member for holding the field magnet terminals. Fi 11 is a perspective view of one of the fie d magnet terminals. Fig. 12 isa diagrammatic view illustrating the circuits of the relay.

A yolre or fieldring 1, of iron, steel, or other highly magnetizable material, which may be continuous, and take a circular or other suitable form, has secured thereto the upwardly extendin field cores 2, held to the ring or yoke 1 y secured by screws 4 a to them. These pole pieces 5 are ta red Surrounding 'each fiel pole 2 is a magnetizin coil 7. As shown by way of example in Fig. 12, all these coils may be connected in series with'each other.- Or they may be otherwise wound and connecte d, so long as. the poles 2 of each pair are similarly magnetized to conjointly magnetire the pole pieces 5, and neighborin pole ieces being of opposite signs as indicated y N and S (nort south), Fig. 1.

Within the central space between the pole tips 6 is disposed a supporting member 8 for the central core 9, here shown cylindrical, and of softiron or other easily magnetizable material, and for the moving system. e core 9 is supported by screws 10 to the vertical legs of the supporting member 8 and bridge pieces 11 connect the ends of these vertical legs. Upon each of these vertical legs is an ear or lug 12 resting upon two of the pole tips 6 and secured thereto by screws 13. Extending vertically through the bridges 11, 11, are pivot screws 14 supporting and inclosing the pivots -15 of the moving system. This moving system comprises the three c0 16, 17 and 18, here shown as rectangular in shape, secured at Patented Apr. 21, 1914.

system comprisa ing through posts 30 flexible conductors exercising an angle to each other and supported by said pivots 15. These coils are disposed in the air gap between the pole tips 6 and the central core 9. As seen in Fig. 12 these coils may be connected in series with each other and have their terminals at binding posts 19 and 20 upon the block of insulating material 21, see Fig. 8, which latter is mounted upon the upper bridge piece 11. The electrical connections from the coils to these binding posts 19 and 20 are by delicate no mechanical control upon the moving system. Carried by and movable with the moving system is a tongue or pointer 22 electrically connected to binding post 23 by delicate flexible conductor 24-; exercising no mechanical control upon the moving system. At its outer end the tongue 22 carries a contact 25 adapted to engage, when the moving system moves, the stationary contacts 26 and 27 carried respectively by the screws 28 and 29 extendand 31 in electrical connection through conductors 32 and 33 with the binding posts 34 and 35 respectively. These posts 30, 31, and binding posts 34 and 35 are supported upon the block of insulating material 36, see Fig. 9, secured by screws 37 upon one of the pole pieces 5. The heads of the screws 28 and 29 are notched and in these. notches are adapted to engage the upwardly extending tips of the leaf springs 38 to keep the screws 28 and 29 and, therefore, the contacts carried by them, in any position to which they may be adjusted.

On the ring or yoke 1 there is secured by screws 40 a block 39, see Figs. 1 and 10, of insulating material, disposed between field windings 7 of neighboring pairs of poles. Upon this block 39 are secured the binding post members 41, 42,. see Figs. 1 and 11, forming the terminals of the field winding circuit.

As herein disclosed, the moving system has no control for biasing it toward any given position or movement in any direction. That is, no spring control or other control is shown for the moving system. It is to be understood, however, that such spring or other control may be supplied, if desired, as illustrated in my aforementioned patent. With the moving system having no control or bias, polarized relay, that is, a relay whose movbias. but whose moving ing member has no member will move in the one direction or the other depending upon the direction of current through the coils.

By providing a plurality of field cores and windings for each pole piece 5, as here shown, the radiating surface of the field winding is greater than where a single pole and coil per pole piece is employed. By this 1 said arrangement for a given magnetizing eifect l the relay is a neutral.

of the field coils, the field coils will remain cooler and will change less in temperature, and, therefore, in resistance. From this fact of a cooler running, and more constant resistance in the field circuit, when a constant potential source of energy is employed for the field circuit, the field strength will vary less than where the temperature of the field winding greatly increases. Since the field strength varies less, the response of the moving system to a current of given strength through the moving coils, will vary less.

By a relay constructed in accordance with the disclosure herein, the field coils change in temperature but slightly, and with the field cores 2 preferably magnetically saturated, the slight change in resistance due to the slight change in temperature produces practically no change in the field in which the moving coils are disposed. While the field cores 2 are magnetically saturated, the pole pieces 5 are of very great cross section and are not saturated thus reducing tendency to magnetic leakage between neighboring pole pieces. Nevertheless, the magnetic lines of each pole piece are concentrated in the gap in front of the pole tips 6. In the aforementioned apparatus which have constructed in accordance with the disclosure herein, with a series connection of the field windings as disclosed, I have used a magnetizing current of nine (9) amperes.

While I have herein shown only two field poles 2 per pole piece 5, it is to be understood that the number may be increased an that the radiating surface of the magnetizing coils will be increased with a still greater reduction in the variations above referred to, and it is to be understood that my invention is not limited to two pole field cores per pole piece.

In operation, the field terminals 41 and 42 are connected to a source of current for magnetizing the field. The binding posts 19 and 20 are connected to conductors associated with or forming a part of any circuit, as a submarine cable circuit. When current passes through these coils in one direction, the tongue 22 is moved in a certain direction to bring contact 25 into engagement with contact 26, for example. When the current passes through the coils in opposite direction, the tongue 22 is moved in opposite direction to bring contact 25 into engagement with contact 27 The binding post 23 and binding posts 34: and 85 are then connected to conductors forming part of a controlled circuit or circuits.
